由于 proxy-target-class="true" 和 <aop:aspectj-autoproxy />，Spring 无法自动装配

Question

我有以下弹簧配置：

<context:annotation-config />
<security:global-method-security jsr250-annotations="enabled"  pre-post-annotations="enabled" proxy-target-class="true" />

<tx:annotation-driven  />

<aop:aspectj-autoproxy />

<context:component-scan base-package="com.web,com.security" />

我在 global-method-security 中启用了 proxy-target-class，因为我想在 controller 中使用 @PreAuthorize 注释（我知道 Spring 团队不鼓励这样做）， 并在保存对象时使用 aop aspectJ 作为 service 中的“拦截器”。

似乎是因为启用了 global-method-security 中的代理配置，并且默认的 aop aspectj 正在使用代理实现。它未能在所有控制器中自动装配 bean。代理代理？

控制器

@RequestMapping(value = "add")
@PreAuthorize("@securityPermission.validatePermission()")
public String add(Model model) {
   //codes
}

我的带有@Aspect 注释的服务类

@SuppressWarnings("serial")
@Aspect
@Service
public class InterceptorServiceImpl extends BaseServiceImplementation implements InterceptorService {
@Autowired
    private LogRepository logRepository;

@Around("execution(* com.repository.CardRequestRepository.save(..))")
@Transactional(readOnly = false, propagation = Propagation.REQUIRED, rollbackFor = Exception.class,timeout = 30)
   public Object checkProcess(ProceedingJoinPoint joinPoint) throws Throwable{
   LOGGER.info("SERVICE : START Process checking Interceptor");

}

存储库类

public interface CardRequestRepository extends JpaRepository<CardRequest, Long>, CardRequestRepositoryCustom {
public List<CardRequest> findByCardholderId(Long cardholderId);

@Query("Select cr FROM CardRequest cr "
        + "LEFT JOIN FETCH cr.cardholder ch "
        + "LEFT JOIN FETCH ch.identityDocument "
        + "LEFT JOIN FETCH cr.program p "
        + "WHERE cr.id = :id")
public CardRequest findOneFetching(@Param("id") Long cardholderId);

}

public interface CardRequestRepositoryCustom {

    public List<CardRequest> findCardRequestWithDatatablesCriterias(DatatablesCriterias criterias);
.....

服务实现类

@SuppressWarnings("serial")
@Service
public class ApprovalActivityServiceImpl extends BaseServiceImplementasi implements ApprovalActivityService {

    @Autowired
    private ApprovalActivityRepository approvalActivityRepository;
    ...
    @Autowired
    private MessageSource messageSource;

    @Transactional(readOnly = true, propagation = Propagation.SUPPORTS)
    public ApprovalActivity findOne(Long id) {
        LOGGER.info("SERVICE : ApprovalActivity findOne id =" + id);
        return approvalActivityRepository.findOne(id);
    }
}

baseserviceimpl 类

public abstract class BaseServiceImplementasi
  implements Serializable
{
  protected transient Logger LOGGER = Logger.getLogger(getClass());
}

是否可以同时使用 aop:aspectj-autoproxy 并启用 proxy-target-class ？或者有人有其他建议吗？ :)

自动接线失败问题已解决

根据@M.Deinum 的建议，我解决了我的自动装配问题，添加了 proxy-target-class="true" 属性：

<tx:annotation-driven /> 
<cache:annotation-driven />
<aop:aspectj-autoproxy />

然后我在带有@Aspect 注释的类中删除@Service。

注意：在 InterceptorServiceImpl 中，我使用 @Service 是因为我希望 @Autowiring 调用存储库/服务 bean

发生的方面类问题：

似乎是因为我删除了方面类中的@Service 注释，aop aspectj 不知何故没有执行，并且我的日志中没有错误。

我解决了我的问题，这似乎是因为在我的存储库类中使用了数据 jpa (JpaRepository)。 这是我的 xml 配置：

<security:global-method-security jsr250-annotations="enabled" pre-post-annotations="enabled" proxy-target-class="true"/> //enabled proxy to use @preAuthorize in controller
<tx:annotation-driven />
<cache:annotation-driven />
<aop:aspectj-autoproxy />
<context:component-scan base-package="com.xxx.xxx.service.serviceimplementasi" />  
<jpa:repositories  base-package="com.csl.cms.repository" entity-manager-factory-ref="entityManagerFactory" transaction-manager-ref="transactionManager"  /> 

数据 jpa 配置：

<!--Spring Data JPA Configuration-->
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" >
        <property name="dataSource" ref="c3p0DataSource-1" />
        <property name="packagesToScan" value="com.xxx.xxx.entity"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="databasePlatform" value="${database.dialect}" /> 
                <property name="showSql" value="true" />
                <property name="generateDdl" value="true" />
            </bean>
        </property>
    </bean>
    <bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />        
        <property name="jpaDialect">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
        </property>
    </bean>

存储库类：

public interface CardRequestRepository extends JpaRepository<CardRequest, Long>, CardRequestRepositoryCustom {
    public List<CardRequest> findByCardholderId(Long cardholderId);

在 CardRequestRepositoryCustom 类中，使用 entityManager 创建自定义保存方法，这样就不会依赖于 JpaRepository 类了。

public class CardRequestRepositoryImpl implements CardRequestRepositoryCustom {

    @PersistenceContext
    private EntityManager em;

 @Override
    public CardRequest customSave(CardRequest cardRequest) {
       em.persist(cardRequest);
       return cardRequest;
    }

我还在方面类中更改了我的切入点类，使用存储库自定义类：

@SuppressWarnings("serial")
@Aspect
@Component
public class ApprovalInterceptorServiceImpl extends BaseServiceImplementasi implements ApprovalInterceptorService {

    @Autowired
    private LifecycleLogRepository lifecycleLogRepository;
    @Autowired
    private ApprovalDefinitionRepository approvalDefinitionRepository;
    @Around("execution(* com.xxx.xxx.repository.repositoryimplementasi.CardRequestRepositoryImpl.customSave(..))")
    @Transactional(readOnly = false, propagation = Propagation.REQUIRED, rollbackFor = Exception.class,timeout = 30)
    public CardRequest checkApprovalProcess(ProceedingJoinPoint joinPoint) throws Throwable{
    LOGGER.info("SERVICE : START Approval Process checking Interceptor");
                System.out.println("SERVICE : START Approval Process checking Interceptor");

                Object messageParam[] = new Object[1];
        Object[] objs = joinPoint.getArgs();
        CardRequest cardRequest = (CardRequest) objs[0];

....

在 aop 方面类中，使用 @Component 自动装配服务 bean，并且不使用 jpaRepository 扩展存储库类，而是使用/创建自定义存储库类和 entityManager 来保存对象。有了这个配置和代码，我的代理类问题就解决了。

如果我在方面类中应用了@Component、@Autowired 并使用了 jpaRepository，则存储库 bean 类无法自动装配。还是不知道为什么会这样。
